[Xenomai-help] POSIX headers and PTHREAD_IPROPAGATE

[Xenomai-help] POSIX headers and PTHREAD_IPROPAGATE

[Jeff Webb]

If I attempt to use PTHREAD_IPROPAGATE in my userspace POSIX skin Xenomai program, I get the following:

irqtest.c: In function ‘main’:
irqtest.c:278: error: ‘XN_ISR_PROPAGATE’ undeclared (first use in this function)irqtest.c:278: error: (Each undeclared identifier is reported only once
irqtest.c:278: error: for each function it appears in.)

Including <nucleus/intr.h> fixes the problem.  I assume there should be a #include in one of the POSIX header files.

I checked the trunk and the v2.2.x branch, and pthread.h includes
nucleus/xenomai.h which includes nucleus/intr.h, so including directly
nucleus/intr.h should not be necessary.

The main header is not included in the user-space case. The patch below
should fix this:
